Abstract: PURPOSE:To make an alarm lamp indicate which of a plurality of different trouble-detecting devices is in action by providing a means for turning the alarm lamp on and off which turns off the lamp at cycles differing between any two trouble-detecting devices. CONSTITUTION:Any of trouble-detecting devices 3, as long as it is in action because of detection of trouble pertaining thereto, causes an alarm lamp 4 to continue to be lighted with breaks in lighting at a certain cycle. For example, when a fault in ignition is identified, with an arbitrary number 3 assigned to this, the output is inverted two times during a period of 10sec set on a timer; as a result, the alarm lamp 4, after being turned off twice successively during a period of 10sec, continues lighting. Similarly, when it is detected that a burner motor has stopped working, the alarm lamp is turned off four times in succession during a 10sec period and continues lighting thereafter.

Title: Paired core inductor
Inventor: TAKEDA FUMIO
IPC: H01F17/00
Filed: 1989-07-03
Abstract: PURPOSE:To obtain an inductor having simple manufacturing steps and small size by exciting two core groups at a zigzag line, and laminating the first core group on a first layer on a board, an insulating layer, an exciting conductor layer, an insulating layer and a second core group thereon in a laminated state. CONSTITUTION:The directions of a magnetic field in a strip core 13 are reverse to each other, and the direction of the magnetic field in a strip core 13 of a part crossing with an exciting conductor 12 is inverted at each folding of the conductor 12. Thus, the diamagnetic field coefficient of the core 13 in a longitudinal direction is increased. The coefficient in a direction perpendicular to the surface of a thin film is large. Therefore, the magnetic field in the core 13 is externally leaked from the side face having small diamagnetic field coefficient. In this case since the magnetic fields of adjacent first and second core groups 15, 16 are reversed, a magnetic path having small diamagnetic field coefficient is formed at a pair of cores crossing with the conductor 12. As a result, the coefficient of the whole inductor is reduced to obtain a large inductance with a small size.
